To all whom it may concern i a Be it known that I, HoivARD 'S. Hoi'i, a citizen of the United States, and resident of Bethel, in the county of Fai'rfi'eld and State of Connecticut, have invented certain new and useful Improvements in Nut or Boltv Holders, of which the following is a specification. 7 v V This invention is an article designed to be slipped over the head of a boltor over a nut to prevent it from turning while the cooperating nut or bolt is being rotated by a wrench or othersuitable tool in screwing the nut on or off. It is designed for use where one of the parts held by the bolt andnut has some projecting part with which my improved holder may engageand be held against rotation, audit is particularly useful where the boltedstru'cture isof such a character that one person cannot gain access to or'conveniently hold the bolt or the nut and'at th same time turn the other. p

Merely as an example of a bolted structure in connection with which my device is especially useful is'the crankcase and transmis sion gear case of some makes of automobiles,

as, forinstance, the Ford, where two men are ordinarily required in bolting 01 1mbolting the parts, one to hold the nut 01' bolt from turning'w h ile the other is turned by'the'other mar-n Gt coursel do not desire to be limited "to this particular use. \Vith some bolted structures I may leave the device on the'nut all of the time and let it serv'e as a nut lock.

The main objectiof my invention is to produce a very simple andinexpensive articlewhichmay be stamped from sheet metal;

which will properly engage with the bolt head or, nut to beheld against rotation in respect thereto; which will properly engage the adj acent part of one of the bolted structures irrrespective of slight va-riations'in'the' distance from said part to th'e bolt-holder; which'cann'ot he accidentally displaced or worked loose when in use; which resists turning strain quickly and equally in both directions; and which resists such strains in the direction of the length rather than transversely of the part which engages the bolted structure, thereby permitting ofthe use of light weight material.

In its preferred construction, it is made from. a sheet metal blank slit-ted to form two plane along their central portions.

contiguous strips integral and in the same The ends of one strip are bent around and securedtog'ether to form a collar or socket part with the nut or bolt-head receiving opening "of such polygonal or non-circular cross section as will adapt it to loosely fit the part received but beheld against rotation in respect thereto. The ends of the other strip constitute ings when are each substantially tangent to said collar and ,areHpreit'er-ably in the planesof adjacent sides or said collar if the latter be polygonal so that they incline in oppositedirections and their ends;

may engage with the clamped part u on slight rotation fin either direction of the d-evice and the bblt or nut held therein.

In the accompanying drawings, 1 have illustrated certain embodiments or inyinvention although it will be evident that changes may be made within thescolp'e er the appended claims without departing from the spirit of my: invention. In these drawingsi Figure 1 is a transverse,section'through a part of a boltedwstructure with ray-inprovedidevice in use thereon; r .1

Fig. 2 is a top plan View; I I

3 is a vertical sectioii'of the deyice;

,Fig. 4 is a plan View of a blank from which the device may be formed; and Fig. 5*is a perspective view or a medifie d form. V I v The form shown in Figs. 1,2 and'3 i's'inade from a blank of substantially tire "form shown in Fig. 4:. This blank 10 has slits 11 extending inwardly from opposite sides to form two strip portions 12'and 13. one of these is shown as being of approximately twice the width of the other. The two strip portions are integral along their centralitself along a line longitudinally thereof and indicated indotted lines in Fig. A: to 7 make the strip of double thickness. The.

7 central unslitte'd portion of the blankbetweenthejstrips'12'and 13 is ofapproximately onesthird'the length. of the "strip 12 so that in bending the strip12 to formthe collar, the strip 13 will likewise be'bent to -f0llow two sides of thehexagon of the collar. The free ends of the strip 12 will therefore lie at approximately 120 t0 each other and willbe approximately tangential to the circle of the collar 14:. T he end portions of the strip 13 thus constitute wings orprojections .15 of double thickness inclined in the same general directionythat is. toward the same vertical surface at one side of the axis of the bolt.

In applying the device, the collar 14 is merely slipped over the bolt-head or nut and the wings 15 will come adjacent to or in en- 1 gagement with a part of one ofa pair of bolted members. .lVith the device in use as shown in Fig. l and upon the bolt-head, a

' person may rotate the nut in loosening'or tightening the same without rotation of the 'bolt. Any tendency of'the' bolt to turn ineither direction will bring the end-of one of 4o sutfi'ciently'thick material be usedj'no folding posite side.yrThisdevice thus' resists not copies tun; ba tentinay be obta iiea m but a tension in the the wings against the surface of one of the bolted'member's' and lock the bolt against rotation. It is quite important to note that to make them of double thickness as shown over is necessary. In Fig. 5 I have shown a slightly modified -form in which the same collarand wings are employed but the" wings; instead of beingof double thickness, are duplicated. Thus the two pair of wings "form a diamond-shaped figure 16 for the hexagonal'collar 13. .Ifall of the wing parts are formed of a' single strip they may be integral with the collar 7 at one side and brazedor otherwise secured to it at then}:-

only by a compression in the direction. of the length, of certain of the essential parts of the'othe'rs. V a
